Electric bed without bed board fabric covering

Abstract

The invention discloses an electric bed without bed board fabric covering. The electric bed comprises a foldable bed frame connected through connecting parts, bed legs connected to the bed frame, a turnable and foldable frame arranged on the bed frame, a driving device arranged on the bed frame, fabric directly covering the multiple frames, and a tensioning mechanism for tensioning the fabric to the surfaces of the frames. The tensioning mechanism comprises an embedded strip, a pipe fitting and a buckling part, when the fabric is in a tensioned state, the embedded strip connected with one endof the fabric is limited in the limiting groove of the pipe fitting on one side, and the other embedded strip connected with the other end of the fabric is limited in the limiting groove of the otherpipe fitting on the opposite side. A traditional wood plate is not adopted, the surface of the frame is directly coated with the fabric with the soft package material, tensioning force is provided through the tensioning device on the frame, flatness of the surface of the fabric is guaranteed, the fabric can be conveniently disassembled without tools, and installation and adaptation of a bed boardare omitted.

Description

technical field [0001] The invention relates to an electric bed, in particular to an electric bed covered with fabric without a bed board. Background technique [0002] The traditional electric bed has the following forms. One is the size-customized structure of the bed board. This structure needs to be composed of bed boards, hinges, mattresses and other materials, which are relatively high in process and material costs; the other is steel wire Mesh structure, the appearance of the bed product of this structure is not good, there is no fabric covering, and the appearance is not good. In addition to this, there is a structure with steel mesh to increase the covering, but the process of this structure is particularly complicated, and the appearance cannot be guaranteed. [0003] Although the existing electric bed has a high degree of automation and can adjust the angle of the bed arbitrarily according to people's wishes to achieve a more comfortable resting posture, there are...

Problems solved by technology

[0002] The traditional electric bed has the following forms. One is the size-customized structure of the bed board, which needs to be composed of bed boards, hinges, mattresses and other materials, which are relatively high in terms of process and material costs; the other is steel wire. Mesh structure, the appearance of this structure bed product is not good, there is no fabric covering, the appearance is not good, in addition to this, there is a structure with steel mesh to increase the covering, but the structure process is particularly complicated, and the appearance cannot be guaranteed

[0003] Although the existing electric bed has a high degree of automation and can adjust the angle of the bed arbitrarily according to people's wishes to achieve a more comfortable resting posture, there are still the following problems: 1) the bed board needs to be prefabricated and has high requirements for strength, so that the manufacturing The cost is high; 2) Lying is uncomfortable, and a soft mattress needs to be placed above the wooden bed board, which is not convenient for the folding use and storage of the electric bed. For example, the Chinese patent No. 201611021896.7 discloses an electric folding bed For bed and electric folding sofa bed, a mattress is placed on the bed board of the folding bed, and the mattress adopts a latex mattress or a memory foam mattress; while another mattress is placed, a mattress fixing device needs to be added, such as Chinese Patent No. 201420384833.8 The patent for invention discloses a mattress fixing device, the mattress fixing device is arranged at the tail of the bed frame, thereby limiting the longitudinal displacement of the mattress
